Shell Mold Casting
Shell casting is a metal casting process similar to sand casting, in which molten metal is poured into a disposable sand mold. However, in shell casting, the mold is a thin-walled shell made by applying a sand resin mixture around the model. The model is a piece of metal with the desired part shape that can be reused to form multiple shell molds. Reusable models increase productivity, while disposable molds allow for the casting of complex geometries.
The process offers greater dimensional accuracy, higher productivity, and lower labor requirements than sand casting, and is often used for small to medium-sized parts with high accuracy requirements.
Shell casting is suitable for ferrous and non-ferrous metals. The most commonly used are carbon steel, alloy steel, stainless steel and copper alloys. Typical parts cast using this process are small to medium in size and require high accuracy, such as gearboxes, cylinder heads, connecting rods and lever arms.

Cast Iron The scrap of the rolls contains many alloy additives such as Cr 2.5% -3.5% Ni - 0.8% - 1.5% Mo - 0.2-0.5%. V 0.2% - 0.8%. The roller consists of a cast iron core with C - 3.2% and a cast steel shell with C - 1.2%. There are always higher alloying elements in the roll shells. Scrap especially profitable for quality steel mills Cast iron alloy scrap price 270 Euro exw
